The invention discloses a high-power wireless charging system based on an LCC resonant circuit, which comprises a transmitting end unit and a receiving end unit, and is characterized in that the transmitting end unit comprises an H-bridge driving structure and a first LCC compensation structure; the receiving end unit comprises a second LCC compensation structure and a rectification filtering structure; the working mode of the high-power wireless charging system based on the LCC resonant circuit is as follows: the turn-off of an MOS tube in the H-bridge driving structure is controlled according to a first square wave signal, a second square wave signal is output to the first LCC compensation structure, and the first LCC compensation structure generates a sine wave, further generates a magnetic field and emits energy; and after the second LCC compensation structure receives the energy, direct current is obtained after the energy passes through a rectification structure and a filtering structure, and the direct
